Lindsay Lohan strips to her bra and panties in a raunchy trailer for her latest film.

The troubled star turns up the heat in the promo for “The Canyons.” The 27-year-old plays Tara, the actress girlfriend of a rich young moviemaker.

She is hiding an affair from her calculating love – and things turn dark when he rumbles her secret.

The preview features a voiceover from Lohan, who asks: “Okay, tell me something – do you really like movies? Really, really like movies? When was the last time you went to see a movie in the theatre – you know, a movie that you really felt meant something to you?”
